TITLE:
BakBone NetVault Backup Denial of Service Vulnerability

SECUNIA ADVISORY ID:
SA36847

VERIFY ADVISORY:
http://secunia.com/advisories/36847/

DESCRIPTION:
AbdulAziz Hariri has discovered a vulnerability in BakBone NetVault,
which can be exploited by malicious people to cause a DoS (Denial of
Service).

The vulnerability is caused due to the npvmgr.exe process passing
fields received in network packets to malloc() without checking for
overly large values. This can be exploited to crash the service by
sending a specially crafted UDP or TCP packet to port 20031.

The vulnerability is confirmed in BakBone NetVault Backup version
8.22 Build 29. Other versions may also be affected.

SOLUTION:
Restrict network access to trusted users only.

PROVIDED AND/OR DISCOVERED BY:
AbdulAziz Hariri of Insight Technologies

CHANGELOG:
2009-09-24: Added reporter link to the "Original Advisory" section.
